Abstract: ABSTRACT OF THE DISCLOSURE         A method for the preparation of a photosensitive silver halide emulsion wherein separate streams of circulationg peptizer solution, circulating peptizer solution, circulated with a power operated pump or pumps, are passed through separated mixing zones in which one is mixed with a solution of a silver salt and the other is mixed with a solution of a halide salt, and said streams are then combined and mixed in a reaction zone so that silver halide crystals are formed by reaction between silver salt and halide salt and the circulating peptizer solution contains increasing amounts of silver halide crystals in course of time, said circulation being continued until a silver halide emulsion of a predetermined concentration has been formed, characterised in that each of said separated streams of peptizer solutin is forced through the respective one of said se-parated mixing zones and into said reaction zone from the nozzle of a venturi-type pump and a stream of the silver salt solution and/or the halide salt solution as the case may be is caused to feed into the respective separated mixing zone under the influence of and at a flow rate dependent on the venturi suction effect of the re-spective venturi-type pump, said venturi pumps being operated under such conditions as to damp high frequency (above ? Hz) pAg oscilla-tions attributable to the inherent characteristics of the pump or pumps used for circulating the emulsion.

Abstract: HIGH CONTINUOUS CURRENT CAPACITY OIL           EXPULSION FUSE               ABSTRACT OF THE DISCLOSURE        An oil expulsion fuse has multiple rupture-resistant fuse wire chambers for providing fault current protection in high voltage distribution circuits in the 25-35 KV range.          In preferred forms, the fuse has a Teflon (a Trademark) core defining three discrete, small diameter cylindrical chambers, each containing a respective fuse wire, whereby sufficient deionizing gas flow is generated upon fusing of the wires to effectively extinguish arcs formed in the chambers, even in t he face of high recovery voltage rates associated with distribution voltages above 15 KV.  The ampacity of the fuse per unit cross-sectional area of fuse wire is increased over single wire fuses by virtue of greater heat loss by transverse convection from the multiple wires to oil in the chambers.

Abstract: THROWER OF TRANSPORTED MATERIALS           Abstract of the Disclosure The thrower is designed for the mining industry and compri-ses a rotatable rotor pivotally connected by means of an at least one connecting rod with a bucket adapted to receive and unload a material. The spacing of the axis of rotation of the rotor from the axis of rotation of the adjacent pivot of the connecting rod is twice the spacing between the axes of rotation of the two pivots of the connecting rod, parallel with the axis of rotation of the rotor.     In operation, the drive of the thrower effects rotation of the rotor and of the connecting rod in the same direction at the same speed, as well as rotation of the bucket in the same direction at a speed which is twice the rotation speed of the rotor. The material is loaded into the bucket in the lower portion of the rotor, since the absolute speed equals zero at this point of its path. The material is thrown of the bucket at a predetermined point of its path, the moment the direction of the centrifugal force aligns with the upper open portion of the bucket, the latter being mounted so that it can be adjusted and retained in a preselected position re-lative to the horizontal plane.

Abstract: TITLE:  TRAY FORMER An improvement in a carton forming mechanism of the type wherein a mandrel is reciprocated through a die assembly to fold the side walls and tabs of an upwardly open carton assembly having perpendicular pairs of side walls.  It is designed specifically for carton blanks having protruding tabs at the ends of both pairs of side walls, so that each side wall is overlapped by a bent tab when the carton is completed.  The folding mechanism includes two opposed pairs of folding irons mounted about parallel spaced pivot axes.  Each folding iron has an arcuate surface to fold a first carton wall relative to the bottom carton wall.  It also includes a radial extension at the outermost edge of the arcuate surface for folding a first tab relative to the first wall.  Radial spacing is provided on each folding iron between the arcuate surface and the shaft mounting it.  This spacing is sufficient to permit second tabs at the ends of second side walls of the carton perpendicular to the folded first side walls to pass between the pivot shafts without interference.  A pair of pressure rollers are rotatably mounted about parallel axes perpendicular to the pivot axes and at an elevation below that of the folding irons, whereby the second carton side walls are folded along their score lines common to the bottom carton wall as each blank is forced between the rollers by reciprocation of the mandrel.  In the resulting partially-folded carton condition, the second tabs remain extended for subsequent completion of the carton.

Abstract: ABSTRACT OF THE DISCLOSURE               A torque regulating alternating current induction motor control system comprising a motor flux sensing coil arrangement mounted on the induction motor stator for sensing the actual flux produced across the rotor-stator air gap of the motor and deriving a motor flux voltage signal proportional to the actual motor flux. An integrating circuit integrates the voltage signal to obtain a feedback sensed actual motor flux signal representative of the actual air gap flux.  An actual torque feedback circuit converts the actual air gap flux and stator current signal to an actual value of torque feedback control signal. A second feedback control loop also responsive to the feed-back sensed actual value of flux converts the flux signal into a   voltage control signal for maintaining a substantially controlled value of rotor-stator air gap flux level.  The first and second feedback control loops are interconnected and coact to maintain operation of the induction motor at a controlled value of torque.

Abstract: ELECTROSTATIC AIR/POWDER    STRIPE APPLICATOR ABSTRACT OF THE DISCLOSURE A powder applicator for applying powder to form a side strip  to the interior of can bodies along side seams thereof.  The powder applicator includes a device for pro-viding a layering effect on the gas entrained powder so that although the powder is normally carried by the gaseous stream it is directed into an orifice of a nozzle as a dense stream with the carrier gas forming a separate layer. In addition, the applicator forms a seal with the interior of the can body to define a limited sealed area within which the powder may pass.  This sealed area contains corona charging pins which are arranged in a longitudinal line so that a maximum charging of the powder may be ef-fected.  Also, a diffused gas is directed into the sealed area to prevent the powder from clinging to the side walls of the sealed area and the charging pins.
